However, these designs often have disadvantages such as poor protection effect, complex structure, and affect on working efficiency. Therefore, it is of great practical significance and application value to develop a fork arm with protection function that can effectively prevent human arms from entering the fork arm and will not affect working efficiency, and the AGV using it.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Embodiment 1
[0022] See also Figure 1-3 A fork arm with a protective function applied to an AGV comprises an AGV body 1 and a lifting assembly arranged in the AGV body 1, a mounting plate 2 is fixedly installed above the AGV body 1, a plurality of first photoelectric sensors 3 are installed on one side of the mounting plate 2, a lower cover front plate 7 is arranged at the front end of the AGV body 1, a second photoelectric sensor 8 is installed on the inner wall of the lower cover front plate 7, the lifting assembly comprises a fork arm lower cover 6 fixedly installed inside the AGV body 1, a lifting mechanism 5 is arranged inside the fork arm lower cover 6, and a fork arm upper cover 4 is fixedly installed on the top of the lifting mechanism 5.
[0023] For further information, see Figure 2 The specific number of the first photoelectric sensors 3 is four, and the four first photoelectric sensors 3 can be divided into two groups. The number of lifting assemblies is also two. The positions of the two groups of first photoelectric sensors 3 correspond to the positions of the two lifting assemblies. By setting the positions of the two groups of first photoelectric sensors 3 to correspond to the positions of the two lifting assemblies, the first photoelectric sensors 3 can monitor the two lifting assemblies more accurately.
[0024] For further information, see Figure 1-3 Two square grooves are provided inside the AGV body 1, and the fork arm lower cover 6 is fixedly installed at the bottom of the square groove. In the initial state, the fork arm upper cover 4, the lifting mechanism 5, and the fork arm lower cover 6 are all located inside the square groove. By setting the square groove and setting the fork arm upper cover 4, the lifting mechanism 5, and the fork arm lower cover 6 to be located inside the square groove in the initial state, the device can be retracted into an integral square when not in use, and is not easily affected by external forces and will not easily cause damage to the user.
[0025] In specific implementation, when users use conventional fork arm lifting assemblies, their hands or other parts are often clamped by the fork arms. Since the fork arms are used for material handling, the strength of the fork arms is generally relatively large. Once the user's arm is clamped, it will cause irreversible serious consequences, so strict protection is required.
[0026] In the present invention, when the user's arm or other part accidentally enters the interior of the lifting assembly from the side, the multiple first photoelectric sensors 3 installed on the inner wall of the mounting plate 2 will be triggered immediately. At the same time, since the first photoelectric sensors 3 are electrically connected to the lifting mechanism 5, the first photoelectric sensors 3 send out an electrical signal to stop the lifting mechanism 5 directly, thereby preventing the user from being pinched by the lifting assembly.
[0027] By setting up the first photoelectric sensor 3 and electrically connecting the first photoelectric sensor 3 with the lifting mechanism 5, the user can get safer protection. At the same time, since the first photoelectric sensor 3 is used instead of the traditional protective plate and guardrail, etc., it will not have too much impact on the operation of the AGV body 1, thereby increasing the practicality of the device.
[0028] Embodiment 2
[0029] Based on Example 1, please refer to Figure 1-3 A fork arm with protective function and an AGV using the same, wherein a lower cover front plate 7 is integrally formed and arranged at the front end of the fork arm lower cover 6, two second photoelectric sensors 8 are installed on the inner wall of one lower cover front plate 7, and the number of the lower cover front plates 7 is two, which are symmetrically arranged at the front end of the AGV body 1.
[0030] For further information, see Figure 3 The specific installation method of the second photoelectric sensor 8 is that the two second photoelectric sensors 8 are simultaneously tilted 30 degrees toward the center of the lower cover front plate 7. The tilted second photoelectric sensors 8 can change their detection direction, thereby expanding their detection range. This arrangement enables the second photoelectric sensors 8 to cover a wider area, increase the probability of detecting the existence of objects or people, and improve the overall safety performance.
[0031] In specific implementation, in addition to easily entering the interior of the lifting assembly from both sides, the user can also easily enter the interior from the front side. Therefore, in the present invention, two second photoelectric sensors 8 in an inclined state are installed on the inner wall of the lower cover front plate 7. At the same time, the second photoelectric sensors 8 are also electrically connected to the lifting mechanism 5. After the second photoelectric sensor 8 detects the human body, the electrical signal is transmitted to the lifting mechanism 5, so that the lifting mechanism 5 stops running, which further increases the safety of the device.
[0032] By providing the second photoelectric sensor 8, the front side of the device can also be protected, thereby further increasing the protection range of the device and improving the safety of the device.
[0033] Working principle: When users use conventional fork arm lifting components, their hands or other parts are often clamped by the fork arms. Since the fork arms are used in material handling, the strength of the fork arms is generally relatively large. Once the user's arm is clamped, it will cause irreversible serious effects, so strict protection is required.
[0034] In the present invention, when the user's arm or other part accidentally enters the interior of the lifting assembly from the side, the multiple first photoelectric sensors 3 installed on the inner wall of the mounting plate 2 will be triggered immediately. At the same time, since the first photoelectric sensors 3 are electrically connected to the lifting mechanism 5, the first photoelectric sensors 3 send out an electrical signal to stop the lifting mechanism 5 directly, thereby preventing the user from being pinched by the lifting assembly.
[0035] In addition to being easy for users to enter the interior of the lifting assembly from both sides, it is also easy for users to enter the interior from the front side. Therefore, in the present invention, two second photoelectric sensors 8 in an inclined state are installed on the inner wall of the lower cover front plate 7. At the same time, the second photoelectric sensors 8 are also electrically connected to the lifting mechanism 5. After the second photoelectric sensor 8 detects the human body, the electrical signal is transmitted to the lifting mechanism 5, so that the lifting mechanism 5 stops running, further increasing the safety of the device.
[0036] By setting up the first photoelectric sensor 3 and electrically connecting the first photoelectric sensor 3 with the lifting mechanism 5, the user can get safer protection. At the same time, since the first photoelectric sensor 3 is used instead of the traditional protective plate and guardrail, etc., it will not have too much impact on the operation of the AGV body 1, thereby increasing the practicality of the device.
[0037] By providing the second photoelectric sensor 8, the front side of the device can also be protected, thereby further increasing the protection range of the device and improving the safety of the device.
